What Hacker News says?
Servo is already embeddable, you can use it in Tauri ( https://servo.org/blog/2024/01/19/embedding-update/ ) or Qt ( https://www.kdab.com/embedding-servo-in-qt/ ).

HN discussionKinda - QML is a programming language, Qt Quick is an UI scene graph (with the main way to use it being through QML) which also "renders everything" and makes by default less effort than widgets to look like the OS. But : - QML can be used with other graphics stack - for instance Qt Widgets like with https://www.kdab.com/declarative-widgets/ or alternatives to the official Qt Quick controls with https://github.com/u…

HN discussion> but that just goes to show how low our standards have become I totally agree. We need to do better. But I still stand with Qt being a good option. There are ways to lower Qt apps binary sizes down to 11MB[1] or 8.3MB[2]. [1] https://www.qt.io/blog/reducing-binary-size-of-qt-applicatio...

HN discussion> A good tree will have something like log(n) depth so normal recursion should be fine. Yes, this is true for comparison/search/sort/bucketing algorithms. But in other applications (e.g. graph theory, networks, sparse matrices) a depth of n, for n elements, can be perfectly legitimate. Or it can even be an edge case, but one you don't want to handle by just segfaulting. > Which reminds me: what is a good tool for an…

HN discussionIt's totally reasonable to lament duplicated effort, but it's worth pointing out that this particular attempt is from a company[0] whose business is Qt consulting - so it's easy to imagine that they might succeed (due to expertise, size, and motivation) where others have not. The post also explains why they started from scratch vs. existing approaches - I'm not qualified to evaluate the claims, but I think they dese…

HN discussionI think the big motivation is now "embedding", i.e. using servo as replacement for webview/cef/etc. So for example you could think Tauri+Servo as Rusts answer to Nodejs+Chromium in Electron. https://servo.org/blog/2024/01/19/embedding-update/ Another example would be Qt which normally uses Chromium for webviews but now there has been work to use Servo instead: https://www.kdab.com/embedding-servo-in-qt/

HN discussionIt seems that they moved it since to a bigger meta issue and it's actively being worked on https://github.com/servo/servo/issues/30593 .
